Everything you need to know before using a VPN

In the digital world, ‘Virtual Private Network’ or ‘VPN’ has become an important tool in online privacy protection, security enhancement and viewing of inaccessible content.

At different times in different countries including China, online access with the help of VPN has also come up in different media.

What is VPN?

A VPN is a type of network architecture that allows a private network to connect to one or more other networks in a virtual way. As a result, public networks also have the benefit of using their own private networks.

Just like any other technology, using a VPN has its own pros and cons, as reported by news site Medium.

What are the benefits of VPN?

Enhancing online privacy: One of the primary benefits of using a VPN is the ability to encrypt the user’s internet connection, thereby avoiding the prying eyes of various ‘ISPs (Internet Service Providers)’, hackers, government officials. A VPN also prevents anyone else from monitoring or interfering with a user’s Internet data over a secure connection.

Anonymous Internet Access: With the help of VPN, the user can hide his IP address and geographical location, thereby making it difficult for various websites, advertisers and online trackers to monitor the user’s online movements. This disguise adds an extra layer of privacy and security, especially when viewing various sensitive or censored content.

Remote access to the Internet securely: VPNs allow access to corporate networks and confidential business information from remote locations. In this case, by encrypting the data exchange between the user’s device and the corporate network, VPN ensures that sensitive information cannot be accessed without permission, even over unsecured Wi-Fi networks.

Protection from Cyber ​​Attack Threats: Apart from encrypting internet traffic, VPNs can protect against various cyber security threats such as ‘man in the middle’ style cyber attacks, ‘DNS spoofing’ and even eavesdropping on user movements over Wi-Fi. And by creating a secure ‘tunnel’ for data transmission, VPNs prevent the risk of tampering or unauthorized access to user data, while also increasing overall cyber security.

All benefits? Are VPNs Risky?

Cyber ​​Security: The primary concern of a VPN is to keep the user’s identity private. As a result, if for some reason a user’s credentials or identity identification information, say username and password, is obtained by someone else, a third party can misuse it to take over his account. Simply put, hacking becomes much easier when VPN user information is in the hands of a hacker.

Slow Internet Speed: One of the most common problems with using a VPN is a slow Internet connection. Since VPNs send data through remote servers and encrypt data transmission, users may experience slow speeds and delays while browsing. Especially in the case of servers that are located far away from the user’s location.

Cost Matters: While many VPN services are available for free or at low cost, premium VPN services offer advanced features and high-speed servers. However, in this case, the money has to be counted. For budget-conscious users, spending pennies on customer service may seem like a luxury, especially if they don’t have a need to unblock content based on privacy or geo-location.

Complexity and technical challenges: Setting up or configuring a VPN can be intimidating to the inexperienced user, especially when it comes to using various advanced features such as encryption protocols, server selection and ‘tunneling’ isolation. In addition, issues such as ‘troubleshooting’ Internet connectivity, ‘DNS’ or ‘Domain Name System’ leaks, or the need for technical expertise in certain applications or device setup, can be challenging for less tech-savvy individuals.

Dependence on the service provider: While various VPN services tout genuine privacy and security benefits, there are risks of being used for nefarious purposes in some cases. There are thousands of VPN software and apps available today. Since the user’s data passes through the hands of the VPN service provider, the user’s data security depends on the integrity of the service provider.

Ultimately, VPNs offer many benefits in terms of protecting user privacy, enhancing security, and accessing content. However, in addition to its advantages, it is necessary to pay attention to how much its disadvantages create trouble for the user.

By understanding the various pros and cons of VPNs, users will be able to make better decisions about whether or not to use the technology, or how to engage with it, Medium wrote in the report.
